AUTOMATIC FLUSHlNG-T ANK,

SBECIFICATION forming part of Letters Patent No. 694,627,dat ed March 4,1902.

Application filed February 6, 1900. Serial No. 4,272. (No model.) 1

To all whom, it may concern.-

Be it known that I, PETER F. GLAOKIN, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State of 5Pennsylvania, have invented certain new and useful Improvements inAutomatic Flushing- Tanks; and I do declare thefollowing'to' be a full,clear, and exact description of the invention, such as will enableothers skilled in lo the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of. thisspecification. My invention has relation to flushing-tanks forwater-closets, latrines, and the like, and has forits object theprovision of novel means for producing an automatic periodical emptyfing of the tank into the closet or other recep- "mole with which it isconnected, so as to flush the same at such.predeterminedintervals-as maybe necessary.

My invention has for its further object the provision of novel means'forsecuring a refill of the closet or the like after the operation of thetank has flushed the same.

My invention consists in the novel construction, combination, andarrangementof parts hereinafter described and claimed.-

Referring to the accompanying drawings, wherein Figure 1 is a verticalsectional view of a flushing-tank embodying my invention,- and Fig. 2 atransverse sectional view of the same. j 5 A designates the body of thetank, which is of the ordinary form and of a size adapted to therequirements of the particular apparatus which is to be flushed. Withinthe tank Aand preferably arranged 40 for convenience of operation nearone end of the same is a supplementary tank B, that rests on the bottomof tank A and reaches nearly to the top thereof. A waste-pipe 0 leadsfrom the bottom of tank B, through the bottom of tank A, and down to thereceptacle which is flushed from the tank.

D designates a bucket, which is arranged within the supplementary tank Band is suspended by a chain E from a lever F, that is 'flushin g-pipewhile it rests on its seat. chain 0 connects the valve M with the leverF. 60

.fulcrumed at G on a cross-barll and is pro- .vided with an adjustableWeight'I, which is secured in position upon the lever F by a set screwK. L designates the flushing-pipe that lead from the tank A to thecloset or other apparatus to'be flushed, and M designates a valve, whichrests on the seat N and which keeps the water in the tank from flowinginto the A A ball-cock P, having an adjustable valve T, is arranged atany convenient point in the tank A, being shown on the bottom of the.tank, so as to produce a noiseless flow of water into the tank, and Sdesignates a pipe leading from a source of supply of water,

such as a main. A ball or floatR is arranged on the end of the lever-armQ of the ballcock, and as the ball rises and falls. with the water inthe tank the ball-cock is opened and closed.

A siphon-tube U passes through the wall of the supplementary tank 13,the bend of the tube being near the. top of said supplemene tary tankand theshorter leg of the tube in the tank A, while the longer legdepends in the supplementary tank B and dips into the bucket D when thelatter is in its elevated position, as shown in the full lines in Fig. 1of the drawings. A smallcnp is fixed on the bottom of the siphon-tube,said cup being lettered V, and a second siphon-tube W is arranged withinthe bucket D, the longer leg of this siphon passing through the bottomof the bucket and serving when brought into 85, use to empty thecontents of the bucket into the supplementary tank.

The water-line of the tank when the latter is full and just about to bedischarged is indicated by the dotted line 0000, and'the Opera tion ofthe apparatus is as follows: When the water flowing through theball-cock-has filled the tank A to the point indicated by the dottedlineocmand has therefore reached the top of the bend of the siphon U, itflows 5 down through the longer leg of the siphon and fillsthe bucket Dup to the point indicated by the dotted line y y. The weight of thewater in the bucket causes the latter to descend, and, drawing down theend of lever F, pulls open the valve M, whereupon the Water in the tankflows down the flushingpipe L and flushes the receptacle to which saidpipe is connected. When the water in the bucket has reached the dottedline y y, it begins to flow through the siphon \V, and eventually theentire contents of the bucket are discharged and the parts will returnto their first position. The Water which flows through siphon W into thesupplementary tank B is carried 01f through the waste-pipe O, and thispipe also serves to carry off any water that might flow from the tank Aover the top of tank B if by accident the parts should fail to work inthe proper manner.

The periods at which the automatic discharge of the tank shall takeplace can be regulated by regulating the flow of water through theball-cock P in the usual manner, and I have suggested the use of aball-cock, for the reason that the gradual shutting-off of water by therise of the ball prolongs the time required to fill the tank andlengthens the time between the discharges of water into theflushing-pipe L.

Having described my invention, I claim 1. In an automatic flushingapparatus, the combination with a main tank and a supplementary tank, ofa flushing-pipe and valve a lever connected to said valve, a bucketsuspended from said lever and within the supplementary tank, asiphon-pipe leading from the main tank to the supplementary tank anddischarging into said bucket and means for automatically emptying saidbucket after it has descended and opened the valve, substantially asdescribed.

2. In a flushing apparatus, the combination of main and supplementarytanks, a bucket adapted to rise and fall and by its movement governingthe flow of Water from the main tank, with a siphon adapted to dischargewater from the main tank into said bucket and a second siphon adapted todischarge the water from the bucket into the supplementary tank,substantially as described.

In testimony whereof I have atfixed my signature in presence of twoWitnesses.

PETER F. GLACKIN.
